717945 ÷ 3 
The aim is to understand the frequency of 3 in 717945.

Step 1:
3 goes into 7 2 times with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 1 after subtracting 6 from 7.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 3

Going ahead to step 2:
3 can be fit into 11 3 times, resulting in a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 23.0
If we subtract 9 from 11, we get 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 3

Going ahead to step 3:
3 goes into 27 9 times with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 239.0
Subtracting 27 from 27 leaves us with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 3

Advancing to step 4:
If we divide 9 by 3, we get 3 and a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 2393.0
If we take 9 away from 9, we end up with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 3

Moving on to step 5:
The number 3 fits into 4 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 23931.0
If we take 3 away from 4, we end up with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 3

Let's proceed to step 6:
3 can be fit into 15 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 239315.0
If we subtract 15 from 15, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
When dividing 0 by 3, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 239315.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
3 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 239315.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 239315.0 with a balance of 0.0.
